VCD激光头是利用激光束来将碟片上的坑点信号转换成电信号的光学机电一体化组件。它可分为二大类:一类是以飞利蒲激光头为代表的全息照像式激光头;另一类是以索尼激光头为代表的普通三光束激光头。无论是台式机还是便携机,激光头的故障率远高于其他部分。
VCD laser head is the use of laser beam to the pits on the pit signal into an electrical and optical optical and electrical components. It can be divided into two categories: one is the hologram-type laser head represented by a Philips laser head; the other is an ordinary three-beam laser head represented by a Sony laser head. Whether the desktop or portable machine, laser head failure rate is much higher than the other parts.
